METHOD OF AND DEVICE FOR FINISHING COVERINGS F BRAIDED MOLDS,

SPECIFICATION forming part of Letters Patent No. 532,280, dated January8,1895. Application filed August 2 4, 1892. Serial No. 1 model) To allwhom it may concern.-

Be it known that I, FRANZ MARKGRAF, of New York city, in the countyandState of New York, have invented a new and useful Method of andDevicefor Finishing the Goverings of Braided Molds, of which the following isa full, clear, and exact description.

My invention relates to an improved method and means for completing thecovering of braided molds.

Inthe manufacture of gimp, trimmings, tassels, and various kinds ofornamental fabric known as passementerie goods, an important feature ofsuch manufactured material, consists in the integral combination withthe woven or plaited fabric of numerous bulbous effects, technicallyknown as braided molds.

The parts just mentioned consist of longitudinally perforated bodies ofwood or other light, strong material, that are externally shaped asfancy may dictate or the style of the trimming they form a part of mayrequire, these being termed molds. The wooden molds are first coveredwith braided fibrous material by a special machine, the 'molds beingintroduced at such intervals as will allow a tubular and contractedportion of the braided covering to be produced between adjacent ends ofthe molds that are thus arranged in continuous order. After the moldsare covered as has been explained, the inter vening tubular portionsthat form the ends of the covering when separated, are severed so as toproduce two projecting end portions of the covering on each mold, thatmust be neatly inserted within the axial perforation of the mold tofinish the latter, and adapt it for use as part of a tassel, or to beinoorpo-- rated with the peculiar trimming goods of which it is to forma part.

Ordinarily, the insertion of the ends of the braided covers on thewooden molds is effected by hand labor, with a smooth style or likeimplement, the operator pressing the implement into the ends of thecovering. This operation is comparatively slow, and therefore expensive.

The objects of my invention are, to provide an improvement in the art offinishing the braided ends of covered molds, and a special machine tocarry into efifect my improved method for effecting said operation,whereby the work will be accomplished in a superior manner, and withmuch greater speed than it was before my invention was produced andemployed for the purpose mentioned.

To these ends, my invention consistsin the peculiar method for insertingthe braided projecting ends of mold coverings, by a special progressivemovement, and the construction and combination of parts in a machine tocarry into eflect the improved method, as is hereinafter moreparticularly described and indicated in the claims;

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar figures of reference indicatecorresponding parts in all the views shown.

Figure 1 is a side view of the novel device preferably employed to carryinto effect the improved method for introducing the tubular ends of thebraided coverings on hollow molds, by a progressive spiral movement ofpart of the device, and also shows a covered mold partly in section,illustrating the operation of the machine. Fig. 2 is a side view of aseries of molds covered by integral braided fabric, showing the molds inone of their forms, ready for separation to be completely covered by aninsertion of their ends by the improved method and machine; and Fig. 3is a transverse sectional view of a spherical mold, showing the braidedcovering applied, and the ends of the latter inserted in the axialperforation of said mold. x

The improved method for inserting the tubular projecting ends of thebraided coverings on hollow molds consists in the intro duction of theseend portions within the axial perforation of the mold, by a rotaryprogress ive movement of a coarse pitched screw-cut style,-which as itis revolved and longitudinally pressed into the fibrous tubular ends ofa covered mold, speedily inverts the ends of said covering, pushing theminto the'perforation of the mold and stretching as well as to rapidlyand neatly finish the covered mold,

without injury to the material composing the of inserting the ends ofmold coverings more speedily and better than by the ordinary method andmeans, it is preferred in order to lessen labor and expedite theoperation, to' employ a simple power driven machine whereon thescrew-cut style is mounted, and adapted for rapid rotation in a properdirection,so that the end portions of the coverings on the molds, may besuccessively applied tothe free end of the revolving style, and said endportions be rapidly inverted and introduced within the perforations ofthe molds.

The machine shown in Fig. 1, represents the preferred form for thedevice that is emv ployed to rapidly rotate by applied power thescrew-formed body of the style, and essentially consists of partsconstructed and combined as follows:

There is an upright column 10, provided, having suflicient weight andlateral dimensions at the base to insure stability, or the column may beclamped or screwed by any suitable means on a table, bench or otherstable support at a proper height from the floor of the room wherein themachine is placed. On the top of the column, a bed piece 11, is securedby one of its ends, so as to project the main portion in a horizontalplane over the enlarged base of the column 10. An upright standard 12,is formed on or secured to the opposite end of the bed piece, whichstandard has a laterally perforated enlargement on its upper end for thereception of one journal end of a spindle 13. Another vertical standard14:, is provided for the loose support of the front end portion of thespindle 13, said standard being projected upwardly from a base block 15,that is seated on the top surface of the bed piece 11, and securedthereto by a screw bolt 16. To retain the front standard in properposition and prevent its lateral displacement, tongues 17 and 18 areformed on the front and rear end portions of the base block 15. Thetongue 18, on the rear of the block 15 has a sliding engagement with amortise in the lower portion of the standard 12, and the front tongue 17is seated on the bed piece 11, between two upwardly projecting abutmentson the latter, one being indicated at 19, in Fig. 1. The spindle 13, hasa grooved pulley 20, mounted on and secured to it between the standards12, let; or said pulley may be integrally formed with the standard, andin service is driven by a belt extended to any source of power androtary motion. From the forward end of the spindle 13, the style 21, isprojected in axial alignment with it, and it is not essential whetherthe body of the style is integrally formed with the spindle, or madeseparately and secured to it by any suitable means. The style 21, issufficiently elongated to render it efficient in service, and has acoarse pitched right or left hand screw formed on its portion thatextends from the spindle to itsfree end, said screw thread being tapereda proper degree toward the outer end, so as to adapt it for a quick andeasy insertion within the tubular fibrous end portions of the moldcoverings.

To render the threaded body of the style capable of producing the bestresults, it is essential that there be a scroll-like formation given toit so that there will be but little height afforded for the thread, anda broad face or peripheral surface produced, as clearly represented inFig. 1, the incline or slope on the screw thread being in a directionaway from the smaller end or point of the style. I n A W As beforeexplained, the perforated molds may be externally shaped as preferred,it being understood that in all of said molds a central perforation isformed with which all parts of the periphery are concentric.

For the purpose of illustrating the improved method and device forfinishing the ends of braided molds, as these parts'are technicallytermed, molds that swell fromeach end toward the longitudinal center areshown at 22, in Figs. 1 and 2; and at 23, in Fig. 3, a spherical mold ofenlarged dimensions is indicated, the fibrous covering 24, in all theviews being tightly drawn over the molds.

In use, the molds having been covered as explained, and separated fromeach other so as to permit projecting end portions 25 to be produced, asrepresented at the left end of the mold in Fig. 1, and at the outer endsof the series of connected molds shown in Fig. 2, the operator graspsthe covered molds one after the other and presses the fibrous tubularend portions of their covers successively against or rather over thefree rapidly rotating end of the screw threaded style 21, which movesfrom left to right, or in the direction of the curved arrow in Fig. 1.

It will be seen that the initial engagement of the small outer end ofthe screw body of the style as it revolves with the rough and possiblyfrayed edge on the braided covering of the end on the mold, will, by anengage ment of the latter with the coarse pitch or incline of the screw,cause said end portion to be inwardly pressed, so as to invert-fold thematerial, the continuation of the operation spreading the tubular endportion of the coverin g so as to force it into close contact with thecylindrical wall of the axial perforation in the mold, thereby drawingall surplus material into the latter, and producing a neat, durablefinish at the ends of the molds as they are successively operated upon,the perfection of which finish adds additional value to IIO the goodsthus finished by the improved ends, of the mold covering by a screw-cutpitched screw formed style, the thread on 16 style. which style issloped away from its point, sub- 2. The herein described method forfinishstantially as described.
